THE SEVENTEENTH CENTURY 245 at its head, seemed likely to be provided by Parliament. But the rapid approach of civil war put an end to all these fine plans, and it was not till the Restoration that they received ayery different fulfilment in the creation of the Royal Society (1682). Though urged by Hartlib to remain in England, Cornenius^saw that there was no hope of doing anything further there, and early in the following year he took his departure and entered into the service of Sweden. The task with which he was now commissioned was the pre- paration of a series of textbooks for the Swedish schools. By this time he was rather tired of writing textbooks and would rather have worked at his pansophic studies. But he saw in Swedish benevolence a chance for the return of his people to their own land, and in spite of many distractions he stuck to the uncongenial work for six weary years. In 1648, the year of the Treaty of Westphalia, he returned to Poland to be senior bishop of the Moravian Church. But peace had brought no relief to the Brethren, and it was only with the greatest difficulty that he was able to prevent their complete dispersion. In the interests of the Church, he was released temporarily from his episcopal duties in 1650, and went to establish a school at Saros Patok in Hungary on the invitation of Count Rakoczy. He immediately made a masterly Sketch of a Pansophic School with seven graded classes, as an indication of the line he proposed to follow. But in actual fact the school, when established, had only three classes, and the teachers proved unwilling to work to his scheme. Yet the four years he spent in Saros Patok were not altogether fruitless ; for among the textbooks he prepared for the school was one which achieved even greater fame than the Janua. This was the Orbis Pictus (or, to give it its fuller title, Orbis Sensualium Pictu$)fTtEF World in Pictures, " a word-list of all the fundamental things in the universe and all the fundamental activities of life represented to the eye." The Orbis Pictus was practically a simplified Janua with the added attraction of illustrations, and was intended for children too young for thtjanua or even for the easier Vestibulum he had written as an introduction to the Janua. It was the first and for a long time the only school book with pictures, and, down to the Nineteenth Century, countless children in all lands made their earliest acquaintance with learning through its quaint pages.
